For the first time I enterd the Rooms, so I went slow and, yeah..
A-90
More skill needed
In order to enter the "Rooms" you need to:
-Go to room 61 in the "Hotel", enter the dungeon and find the lever. Once you pull it, head back to room 60. Behind one of the closets there should be a labirynth, and at the end, door A-000
-To open the door to the Rooms you need a skeleton key (can be purchased at Jeff's Shop) and 2 lockpicks
